The Newton Men's Sir Isaac Neutral Guidance Trainer Shoe is designed for runners of all levels, including beginners, who are committed to Natural Running. It is ideal for runners transitioning from a heavy heel strike to a comfortable midfoot landing position. Whether you follow Chi, Pose, Evolution, barefoot running or just want to run better, the Isaac allows you to run naturally — with greater efficiency and less overuse injuries (like achilles tendonitis and plantar fasciitis). Recommended for any running distance, walking or general fitness. What is the difference between the Isaac Trainer and the Performance Trainer? The Guidance Trainer has: Beveled Heel and Toe: guides footstrike easily into the midfoot/forefoot Beveled Lugs: feels smoother, more stable and gradual in the forefoot Wider midfoot/forefoot and lugs: added stability, creating a softer feel Midfoot Chassis/Shank: added support and stability Carbon Rubber Outersole: increased durability Closed Mesh on Upper: keeps small debris out For new customers, Newton shoes tend to fit smaller that many common running shoes. With every shoe there is an adjustment period. Note: This product comes NEW and in un-used condition, but, may not come in the original manufacturers packaging.
